OPERATION
Detergent Solution Tank
The solution tank is provided with an inspection opening. This permits cleaning of
the exit point of the detergent solution.
Be sure that the cap is well tightened after the cleaning.
Open the screw plug (1) placed in the rear left part of the machine and fill the de-
tergent solution tank with clean water at a maximum temperature of 50°C (122°F).
Add the liquid detergent in the percentage and conditions recommended by the
manufacturer. To avoid excessive foam presence, which could cause problems to
the suction motor, use the minimum percentage of detergent. Screw down the plug
to close the tank.
Always use low foam detergent. To avoid foam presence, before starting working
operation, add into the recovery tank a minimum quantity of anti-foam product.
Never use pure acid.
